Architectural palimpsests occur when a building is torn down, but leaves a print on the adjacent building. You can see the placement of the stairs, the color of the rooms. Years ago, when I was teaching art to young children, I asked a class to draw maps of their homes - to show the arrangements of the rooms inside the house. One girl, from a somewhat dysfunctional family, was visibly upset and did NOT want to draw her home. I think she was afraid what it would reveal about her family (of course I discretely changed the assignment for her). But I feel that these palimpsests expose a view of hidden lives - like my Reliquary for my mother. You see things that were never meant for public view.
